feat(spmd): add support for FFA_EL3_INTR_HANDLE_32 ABI
When Group0 Secure interrupts in secure world get trapped to S-EL2
SPMC, FFA_EL3_INTR_HANDLE ABI is invoked by SPMC to delegate
interrupt handling to EL3 firmware (i.e., SPMD).
SPMD further delegates to platform handler which successfully handles
the Group0 secure interrupt before returning control to SPMC.
